This bicycle tour brings you from the northern park entry in Pak Chong district of Nakhon Rachasima province to the radar station at Khao Khiao via the Heo Suwat waterfall and then back to Mu Si. 

The tracks climbs from below 400 m up to more than 800 m over the first 10 Km. It continues up and down hill, passing the visitor center, toward the crossing at the training center.

Back at the crossing you turn south and a couple of hundred meters further at the Ranger outpost, you turn left towards the Thai Army Control and Reporting Center high upon Khao Khiao (aka Khao Rom). After having reached the highest view point, you descent back the opposite way to the cross road at the Ranger Station and turn here north, back to Mu Si. The bicycle track is about 75 Km long and is paved all the way. Biking takes about 4-5 hours.

Be aware that the road towards the CRC is often closed for land slides in the months September and October.

Khao Rom is a 1,351 m high mountain and the highest peak of the San Kamphaeng Range, located between Eastern Thailand and Isan. Khao Rom was also known as "Green Hill" (Khao Khiao) during the Vietnam War. In the period 23 Feb 1966 - 31 Mar 1971 there was a US military Air Defense Radar Station of the 4th Detachment of the 621 TCS (Tactical Control Squadron), Khao Khiao RTAB TH 'Dressy Lady' Control and Reporting Center (CRC), at the top of the mountain which is located roughly midway between Bangkok and Korat. The US soldiers were housed in cabins leased from Tourist Authority Thailand in a squadron area. The primary mission of the CRC was flight follow of departing/recovering tankers and B-52s to U-Tapao. On departure the CRC tracked them to a handoff point where they would go over to Lion or Brigham. Returning Lion and Brigham would hand them back to the CRC for recovery to U-Tapao. Occasionally there would be an opportunity for a tanker hook-up with departing fighters, but it was primarily flight follow. Other units at the site were STRATCOM, STRATCOM-USSAC-THAI, 1st Signal, 7th Radio Research Field Site (RRFS), 442nd Signal Battalion. The mountain is surrounded by forests and, like a great portion of the San Kamphaeng Range, it is part of the Khao Yai National Park area. The former US CRC is now run by the Royal Thai Armed Forces and is guarded by the military. Although the highest point of the mountain is not accessible to the public, there is a viewpoint near the entrance. (Sources: us-seasia.tripod.com, squawk-flash.org/dressylady/khaokhieo.htm)
